Former VWDieselParts.com Forum

I have a 99 Passat TDI. It has done 115k on the original injectors.
When should I renew the injectors. I posted this on the general vw forumand had no replies. There are differing views on when they should be replaced.What's right?

if your engine is not smokig black smoke and runnig smooth, no need to change them
